Purpose and Procedure for Drafting the Document
What is a Fertilizer Spreader Calibration Report?
A fertilizer spreader calibration report documents the process and results of calibrating a spreader to ensure it applies fertilizer at the desired rate and uniformity. It is essential for efficient and environmentally responsible farming.
Why Use This Template?
This template provides a structured format to record calibration method, target and measured application rates, uniformity coefficient, and spreader settings. It helps maintain accurate records for compliance and best practices.
Key Information Captured
The report includes report identification, calibration details (method, rates, uniformity, settings), observations, and signatures of the operator and agronomist.
Pre-Season Preparation
Before the application season, calibrating spreaders ensures that fertilizer is applied accurately from the start, reducing waste and environmental impact.
Equipment Change or Repair
After repairing or adjusting a spreader, calibration verifies that it still operates within acceptable tolerances.
New Equipment Setup
When a new spreader is purchased, calibration establishes baseline settings for different fertilizer types and application rates.
Record Keeping for Audits
Calibration reports serve as evidence of due diligence during farm audits or inspections by regulatory bodies.
- 1
Check Spreader Condition
Inspect the spreader for any visible damage or wear that could affect calibration.
- 2
Perform Calibration Test
Conduct a calibration test using a method such as a pan test or belt test, and measure the actual application rate.
- 3
Adjust and Document
Adjust spreader settings if needed to match the target rate, then record all parameters and results in the report.
Photo Report Generator
Attach photos of the spreader and calibration setup to your report for visual verification using the photo report generator.

Frequently Asked Questions about Photo Reports and Photo Tables
What information is needed to complete this report?
You will need the spreader identification (make, model, serial number), calibration method, target and measured application rates, spreader settings, and any observations. Signatures from the operator and agronomist are also required.
Who should sign the calibration report?
The operator who performed the calibration and the agronomist overseeing the process typically sign the report. If no agronomist is involved, the operator's signature may suffice.
Can I use this template for different types of spreaders?
Yes, the template is designed to be flexible and can be used for various spreader types, including broadcast spreaders, drop spreaders, and pneumatic spreaders.
How do I measure the uniformity coefficient?
The uniformity coefficient can be calculated from collection pan data. The template allows you to enter the value manually; you can also describe the method in the observations section.
Is this report accepted for regulatory compliance?
While this template provides a thorough record, specific regulatory requirements may vary. It is advisable to check with local agricultural authorities for any mandatory formats.
